Sakai Open Academic Environment (OAE) 1.4.0 release
RELEASE DATE: 1 August 2012
The Sakai Community is pleased to announce the release of the Sakai OAE version
1.4.0.
Sakai OAE is an open-source platform that promotes collaboration and sharing
between users and interoperability between systems. It embraces a new vision
for academic collaboration informed by the needs of learners, teachers and
researchers. OAE provides academic networking capabilities that encourage
people to connect and participate actively in communities that span beyond the
traditional boundaries of classroom and institution. Powerful content authoring
capabilities permit mash-ups and remixable experiences of ideas, connectivity,
dialog and media. Enhanced search capabilities aid discovery of people and
content. A widget-based architecture simplifies both development and
integration with external systems.
WHAT'S NEW
OAE 1.4.0 introduces the following new refinements:
Multiple improvements to widget loading
Improved loading of 3rd party and jQuery components
General reduction in the number of HTTP requests (CSSEmbed, etc.)
When embedding images on a page, processed images are now used.
Improved caching
Streamlined server logging
we also fixed some bugs too: http://bit.ly/OC842P
An OAE 1.4.0 vs 1.3.0 test comparing total requests and total data transfers
required to display six common pages (no gzipping), both with an empty cache
and a primed cache, suggests
a 50% reduction in the number of requests, both for an empty and a primed
cache. When the cache is primed, OAE now averages around 5-6 requests per page.
with a primed cache, a reduction in the amount of data transferred over the
wire by almost 2 orders of magnitude, dropping from an average of 350KB to
about 5KB.
a reduction in the size of non-cached Ajax requests.
